Abstract : Crystallographic engineering of single crystal relaxor-based ferroelectrics was used to design broadband, compact, high power, low frequency transducers. A unique face shear-mode produces a d36 coefficient that has demonstrated the ability provide a robust projector that meets these qualifications. This work looks at expanding the operating bandwidth and/or acoustic power output that may be achieved by designing multi-mode transducers using multiple d36 crystal geometries or combinations of d36 and other crystal cuts.
